dsh-width-tiers

A client plugin for the DeepSeek Harness Web GUI that adds chat content width tiers with a floating picker button (bottom-right, above the composer): 标准 / 中等 / 宽 / 超宽 / 全宽 (standard / medium / wide / ultra / full).

Why

The DSH Web app hard-codes a readable content width on the conversation root (--dsh-chat-content-width: 748px). That caps the message column — and every table inside it — at 748px no matter how wide your window or panels are, so wide tables always need horizontal scrolling.

This plugin overrides that variable per tier:

Tier	Content width	Sidebar
standard 标准	748px (app default)	untouched
medium 中等	960px	untouched
wide 宽	1280px	untouched
ultra 超宽	1400px	untouched
full 全宽	100% (fills the window)	collapsed to the icon rail

The choice persists in localStorage and is restored on the next visit; the menu highlights the current tier, and the button's five level-bars show it at a glance.

Install

dsh plugin --profile web add dsh-width-tiers

Then register it as a loader entry in ~/.dsh/profiles/web/cordis.patch.yml:

- insert:
    - id: dsh-width-tiers
      name: dsh-width-tiers

Restart dsh web (the plugin loads at boot) and hard-refresh the page (Ctrl+Shift+R). A round button with five bars appears at the bottom-right.

Installing from a local checkout: dsh plugin --profile web add file:/path/to/dsh-width-tiers. Local-development gotcha: file: dependencies are copied into the profile's node_modules (pnpm does not symlink them). After editing the plugin source, re-sync the copy (e.g. rsync -a --delete --exclude .git /path/to/dsh-width-tiers/ ~/.dsh/profiles/web/node_modules/dsh-width-tiers/) or re-install after removing it, then restart dsh web and hard-refresh.

Usage

• Click the round button → pick a tier; the current one is highlighted.
• full collapses the sidebar to the icon rail through the app's own toggle — it is never force-hidden or locked: click a rail icon any time to expand it, and it stays expanded.
• Non-standard tiers also close the details panel (re-closed automatically if reopened); standard leaves everything to the app.

Language

All picker copy (tier labels, button aria-label and title) follows the app's Settings → Language (中文 / English), through the app's own locale service. Switching the language re-renders the button and menu immediately; when no explicit language is chosen the app falls back to the browser's language, and Chinese is the last resort. No plugin-side setting needed.

How it works

• The element that defines --dsh-chat-content-width is located at runtime (the first element whose computed value is non-empty) and the tier is applied as an inline override — no hashed class names, so it survives bundle upgrades.
• Panels are driven through the layout service (ctx.layout), never by simulating clicks.
• The sidebar is only ever collapsed by the full tier; returning to standard restores it only if this plugin collapsed it.
• Dictionaries are registered with the app's locale service (ctx.locale.register / bind) and re-rendered through its change subscription, so the copy always matches the app's active language.

Limitations

• Content width cannot exceed the window: on a narrow window, wider tiers are capped by the available column. Use full (which also collapses the sidebar) for the maximum.
• Requires the DSH Web client plugin system (dsh ≥ 0.1.0-rc.x with a web profile).

Uninstall

dsh plugin --profile web remove dsh-width-tiers

Remove the dsh-width-tiers row from ~/.dsh/profiles/web/cordis.patch.yml, then restart dsh web.
